STRIP SHINGLE.

`origini-i1 No. 1,326,899, dated To all who/m, it may concern:

Be it known that I, HERBERT ABRAHAM, a. citizen of the United States,residing at the city,.county, and State of New York,

have invented certain new land useful Improvements in Strip Shingles, ofwhich the following isa specification.

One of the objects of the inventionis to vproduce strip-shingles of suchform that'a given area of roof deck can be covered and made watertightwith a smaller quantity of material than has heretofore been required.

Another object is to produce a shinglestrip"having a plurality of'tabsalong itsl up er edge. A still further object is to cut the-strips sothat the cutaway portions of one rowA of shingles| forni the tabs `ofthe adjacent row. f A further object is to 'eliminate the likelihood ofcurling by removing the .corners of the shingle-,like portions andutilizing the material cut away from onestrip to form the tabs of anadjacent strip.

This invention pertains particularly to an improvement instrip-shinglesof the type having their lower edges slotted at intervals so that whenlaid iii overlapping courses they will simulate the appearance of indi-4j vidual shingles. a

Heretofore in the art, with strips of that type, having, for example,substantially the Morel generally considered, my improved shingle-stripmay be defined as one having parallel straight longitudinal edges, withhe lower edge indented at intervals by recesses leading into slots'toprovide shingle-r invention relates to strip-shingles of. .Prepledroofing j.

Figure 21s a "view of a ,fragment of a sheet of prepared roofingindicating the preferred method of manufacturing the shingle-strips;

gigure 3 'is' a section of laid strip-shingles, an i a Figure 4 is amodication showing a stripshingle having semicircular shaped tabs.

According to my invention, I take a sheet of prepared roofing and cutout .,a plurality of rows of small oblongishaped openings 1, theopenings in any one rowv being preferably, though not necessarily,disposed midway between the openings in the adjacent rows. In thecompleted `.strip-Shingles, shown in F iguresl and 4, these,l openingsform the slots between the adjacent shinglelike portions. The sheet isIalso severed along wavy-like lines 2'intersecting an end of theopenings,as shown in Figure 2. The cutting of the lines 2 may beperformed either separately yor simultaneously with the cutting of theopenings lThis produces aV multiple shingle-strip having a seriesof tabs3 along its upper edge, and having its lower edge formedof a. series ofstraight lines extending parallel to the major axis of the strip andseparated by slots opening into cut-out portions or recesses whichsubstantially correspgnd in shape to the tabs, said tabs on lthe upperedge being preferably, thoughnot necessarily, disposed in staggeredrelation to the cut-out portions of the lower edge. The strips aregenerally cutinto blocks of four shingles each, as indicatede in Figure2, to form the completed article/shown in Figures 1 and 4. It will beseen by reference to Figure 2 thatthe tabs r3 of any one strip areformed of material cut out to provide the recesses of the adjacentstrip, which recesses respectively lead into the slotsof said strip. Tnthis way thev shingle-strips are produced without lossof material otherthan that caused bythe cutting out of the openings 1 andfbthel necessaryl trimmingjof the sheet.- 4

By varying the character( of*` the cutting line 2 the tabs 3 may bemade-of 'other thany triangular shape, for example, they `may .be`

of'semi4circular sha-pe,` `asishown inFigure 4L Preferably the stripsare fastened to the roof deck by means `of nails driven" above the slotsas illustrated .in ligulre 3, it being understood that the Lnails of"*each lowerl course are covered by the course next above. When strips ofthe proportions shown are used the nails will penetrate thrdughthe tabsof the strip below, in which case the tabs will n function as nailingtabs. A Howeverfif wider strips are used, then the nails vwill penetratethe under strip through the bodyi of the y strip.

Asshownin thedrawingdl the depth of i the combined recessesand slots,which 'define the extent that the strip is tc be exposed the width of tofthe strip `To securelthe greatest econ-- muyy of material I.` refertoiemploy'stripsl be substantially one-half of when; laid ma 9 heindividual shingle :portions vi'flfierein` the width 0themstrip,excluding the tabs, is twice the depth of the combined reg-'cesses and slots and laid inthe manner It will beseen that the`overlap `measured vertically between the uppery ends of the slots ofany course andthe uppermost portion of l the next underlying course`will, at the mint mulini be ,equal to the altitude of,` the tabs, thusproviding substantially the same protec'- l` tion against leakage atthose points as` is afforded b"-`v the old type of shingle-strip` 'ofvcorrespon ing over-all' width, but with' a considerable savingy ofshingle material.

c, Obviously, however,y the width mofthe body l bined recesses and slotswill v-beless than oneu iss tion.

portion, of the strip: may,` be increased without departing fromthescope ofl `my inven-n Thus it may be advisable to usefwiderystrips'in' which case the'depth of the comhalf .ofthevwidthfofA the bodportion. This will require a corresponding y greater quan#` tity ofmaterial tolcov'er a given-area of roof deck, but `will still` result in.a substantial;
